Both your nutritional needs (the food and water) and your metabolism (how fast your body converts food to energy) change at this age. Your metabolism gets slower. Women lose about half a pound of muscle per year starting around the age of 40. That makes losing weight even more difficult. Some of the changes women experience are due to decreased hormones, reduced activity level, and medical conditions.
Nutrition interventions that target mothers alone inadequately address women's needs across their lives: during adolescence, pre-conception, and in later years of life. They also fail to capture nulliparous women. The extent to which nutrition interventions effectively reach women throughout the life course is not well-documented. In this comprehensive narrative review, we summarized the impact and delivery platforms of nutrition-specific and nutrition-sensitive interventions targeting adolescent girls, women of reproductive age (non-pregnant, non-lactating), pregnant and lactating women, women with young children<5 years, and older women, with a focus on nutrition interventions delivered in low- and middle-income countries. We found that though there were many effective interventions that targeted women's nutrition, they largely targeted women who were pregnant and lactating or with young children. There were major gaps in the targeting of interventions to older women. For the delivery platforms, community-based settings, compared to facility-based settings, more equitably reached women across the life course, including adolescents, women of reproductive age, and older women. Nutrition-sensitive approaches were more often delivered in community-based settings, however, the evidence of their impact on women's nutritional outcomes was less clear. We also found major research and programming gaps targeting overweight, obesity, and non-communicable disease. We conclude that focused efforts on women during pregnancy and in the first couple of years postpartum fails to address the interrelation and compounding nature of nutritional disadvantages that are perpetuated across many women's lives. In order for policies and interventions to more effectively address inequities faced by women, and not only women as mothers, it is essential that they reflect how, when, and where to engage with women across the life course.
To help you learn how to eat healthfully, start with the U.S. Department of Agriculture's (USDA) dietary guidelines system, which you can find at http://www.mypyramid.gov. The MyPyramid system, which looks somewhat like the familiar food pyramid of old, offers guidance based on individual needs and replaces "serving" recommendations with actual amounts of food. It also emphasizes the importance of balancing nutritious (and tasty!) food choices from all food groups every day with daily physical activity.
Women, as we age, are also more susceptible to the breakdown of our bones, which may result in osteoporosis over time. Genetically, women have a particularly high risk of osteoporosis compared to men, so it’s recommended that women monitor their calcium intake to be sure they’re getting enough. Weight training is another great way (and my favorite!) to build bone density, which is another great reason you should hit the weights!
Don't take dramatic steps alone. You need to work closely with an experienced health care professional to lose weight, particularly if you have other medical problems, plan to lose more than 15 to 20 pounds or take medication on a regular basis. An initial checkup can identify conditions that might be affected by dieting and weight loss. Make sure you find out how much experience your health care professional has dealing with nutrition. It's not always well covered in medical schools. You may want to talk to a registered dietitian before embarking on a diet.
Nutritional supplements are items that are usually considered non-food items that are used to enhance your nutritional program. Supplements may include, but are not limited to, vitamins, minerals, bars, and energy drinks or sports nutrition products to enhance performance. Supplements should be used alongside a healthy diet, but not replace it. To find a dietitian in your area that can assist you with supplements, go to www.eatright.org.
Consumers can make wise choices for nutritional supplementation by consulting professional nutritionists and naturopathic physicians. Nutritional supplements are best added into the diet slowly, starting with small dosages and working up to the manufacturers' recommended amounts over time. Also, some supplements, such as herbal medications that may stimulate processes in the body, are best taken intermittently, allowing the body occasional rest periods without the supplement. To avoid unfavorable interactions, nutritional supplements are best used moderately and individually, rather than taking handfuls of capsules and tablets for various needs and conditions at the same time. Finally, consumers should be wary of excessive or grandiose health claims made by manufacturers of nutritional supplements and rely on scientific information to validate these claims.
In between meals, go ahead and have a snack. "When you go too long in between meals without eating, it is difficult to go into your next meal in control and avoid overeating,” Julia Levine Axelbaum, R.D., L.D., Bariatric Dietitian at NewStart Clinic, tells SELF. Of course, you'll want to be thoughtful about the kind of snacks you opt for. She explains that those that are high in protein, fiber, and complex carbohydrates will give you the energy you need to get through the day and keep you satiated from one meal to the next. On the other hand, those that are high in refined carbs and sugar will give you a sudden blood sugar spike that will eventually cause you to crash and feel even more tired.
